How to use:
This is how I use the bugs. It may not be correct compared to real procedures.

The required bugs you need to set for the call out to work is Bug_2 to V1 speed, Bug_3 to Vr speed, and set the MCP speed to V2 (if you use V2 callout).
You can set the other bugs to whatever you prefere.

Demo:

Known bugs/limitations:
- Speed bugs can only be set on Captains side.
